Susceptibility of Campylobacter jejuni and Campylobacter coli to macrolides and related compounds.

The susceptibility of 105 thermophilic campylobacters from human and swine origins to eight macrolides and related compounds was tested. Erythromycin, josamycin, clindamycin, and ASE 136 BS (a new erythromycin derivative) were the most active against the human strains. The swine strains were highly resistant, except to pristinamycin. The human Campylobacter coli strains (except for two strains) behaved like the C. jejuni strains.
